My favourite was the last Battle of Alberta. Has it really been twenty years since Calgary and Edmonton met in the playoffs?

Edmonton Oilers vs. Calgary Flames (1991)

The last Battle of Alberta in the playoffs was epic. The defending Stanley Cup champion Oilers met the Flames in the first round. Gretzky, Kurri and Coffey were gone but many of the pieces from the Oiler dynasty, including captain Mark Messier were still in place.

After trailing 3-0 in the first period at the Saddledome, the Oilers came back to take the lead. The Flames tied it up at 4-4 to send the game to overtime. Just before the seven-minute mark of OT, Esa Tikkanen stickhandled from his own zone to the Flames faceoff circle and fired the puck past Flames goalie Mike Vernon to win the series with his third goal of the game.
